Due to increased complexity in regulation requirements as well as corporate environmental green initiatives, more and more manufacturers find themselves exploring Laser as a coding alternative, but don’t know where to start. Laser coding has the ability to provide a non-contact application of permanent high-resolution mark that is more resilient than traditional coding for better brand protection and code recovery. We will look at different laser technologies and their marking characteristics on various substrates and discuss how they have resolved specific application issues. We will decipher the “Art” of laser marking by exploring optimization strategies in laser settings and substrate composition, including the use of additives, in an effort to maximize code quality.
